I’m building a custom site that must speak fluently with the blockchain. The front-end is already in place, but right now it’s just a beautiful shell; what I need is the Web3 plumbing and the smart-contract backbone that will let users connect, transact and interact securely. Here’s the scope as I see it today — Integrate the most common wallets (MetaMask, Trust Wallet, Coinbase Wallet and any others you recommend) so a user can connect in a single click, sign messages and approve transactions without leaving the site. — Write and deploy Solidity contracts that cover token creation, governance/voting and staking functionality. The exact mix of those modules will depend on the business logic we confirm together, but I want the architecture to be modular so new features slot in easily. — Wire the contracts to the front-end with Web3.js or ethers.js, ensuring events, state updates and error handling are rock-solid across desktop and mobile browsers. — Provide a short hand-off guide and clean, commented code so my internal team can extend or audit anything later. Acceptance criteria • A user can connect at least two wallets and complete a full test transaction on a public testnet. • Contracts are verified on Etherscan (or the equivalent explorer) and unit-tested with hardhat or truffle. • Front-end reflects on-chain state changes in real time without page refresh. • No critical findings when run through OpenZeppelin’s defender or another automated security audit tool. If you have a track record with Solidity, EVM chains and wallet integrations, let’s bring this site to life.
